Sweet flower butters can be made with roses, violets, lavender, and pineapple sage and are a treat on egg breads, sugar cookies, or as a mystery filling between layers of pound or sponge cake. Not all edible flowers are equally tasty. Before you prepare the blossoms taste a few petals to make sure they please your palate.
Making any flower butter involves the same process. First, remove the petals from the flowers and wash them well in cold water—check for critters. Gently pat them dry in a towel or dry them in a salad spinner. Using a very sharp knife, mince the flowers and any leaves. (Mincing is easier if you roll the blossoms into a small ball before cutting them.)
Cut a stick of room-temperature butter into 6 or 8 pieces and then mash them with a fork. When the butter is fairly soft, slowly incorporate any flavorings and the flowers and leaves. With a rubber spatula put the mixture into a small butter crock or decorative bowl. Refrigerate until serving time.
Flower butters can be frozen in sealed containers for 2 months.
